<h2>
Version 2.3.2
</h2>
<h3>
Summary of main changes
</h3>
<h4>
Bug fixes
</h4>
<p>

Version 2.3.1 changed the way binary and text content types were determined as far as the View Results Tree Listener was concerned:
originally everything except "image/" content types were considered text, but 2.3.1 introduced a check
for specific content types. This has caused problems,
as several popular types were omitted and these were no longer shown by default in the Response tab.
Rather than try to list all the possible text types, JMeter now just checks for the following binary types:

<ul>


<li>
image/*
</li>


<li>
audio/*
</li>


<li>
video/*
</li>


</ul>

All other types are now assumed to be text.

</p>
<p>

JMeter 2.3.1 introduced a bug in the Cookie Manager 
- if "Clear Cookie each iteration" was selected, all threads would see the same cookies.
This bug has been corrected.

</p>
<h4>
Improvements
</h4>
<p>

The Proxy server can now record binary requests.
By default the content types
application/x-amf and application/x-java-serialized-object
will be treated as binary and saved in a file.
To change the content types, update the property 
<b>
proxy.binary.types
</b>
.

</p>
<p>

The CSV Dataset configuration element has new file sharing options: per thread group, per thread, per identifier.
This allows for more flexible file processing, e.g. each thread can process the same data in the same order.

</p>
<p>
Switch Controller now works properly with functions and variables, 
and the condition can now be a name instead of a number.
Simple Controller now works properly under a While Controller
</p>
<p>
CSV fields in JTL files can now contain delimiters. 
CSV and XML files can now contain additional variables (define the JMeter property 
<b>
sample_variables
</b>
).
</p>
<p>
Response Assertion can now match on substrings (i.e. not regular expression). 
Regex extractor can operate on variables.
</p>
<p>

XPath processing is improved; Tidy errors are handled better.

</p>
<p>
Save Table Data buttons added to Summary and Aggregate reports to allow easy saving of the calculated data.
</p>
<p>

HTTP samplers can now save just the MD5 hash of responses, rather than the entire response.
As a special case, if the HTTP Sampler path starts with "http://" or "https://" then this is used as the full URL,
overriding the host and port fields.
The HTTP Samplers can now POST multiple files.
Webservice(SOAP) Sampler can now load local WSDL files using the "file:" protocol.

</p>
<p>

A simple HTTP Cache Manager has been added. This needs further development.

</p>
<p>

View Results Tree Listener now uses Tidy to display XML.
This should allow more content to be displayed succesfully.
It also avoids the need to download remote DTD files, which can slow the rendering considerably.

</p>
<p>

MailReader sampler now supports POP3S and IMAPS protocols. Individual mails are now added as sub-samples.

</p>
<p>

Various improvements to the BSF Sampler: now supports Jexl, and Javascript bug works properly.
Added BSF PreProcessor, PostProcessor and Assertion test elements.
All now have access to "props" JMeter Properties object.

</p>
<p>
Number of classes loaded in non-GUI mode is much reduced.
</p>
<h3>
Known bugs
</h3>
<p>

The Include Controller has some problems in non-GUI mode. 
In particular, it can cause a NullPointerException if there are two include controllers with the same name.

</p>
<p>
Once Only controller behaves OK under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).
</p>
<p>

The menu item Options / Choose Language does not change all the displayed text to the new language.
To override the default local language, set the JMeter property "language" before starting JMeter. 

</p>
<h3>
Incompatible changes
</h3>
<ul>


<li>

To reduce the number of classes loaded in non-GUI mode,
Functions will only be found if their classname contains the string
'.functions.' and does not contain the string '.gui.'.
All existing JMeter functions conform to this restriction.
To revert to earlier behaviour, comment or change the properties classfinder.functions.* in jmeter.properties.

</li>


<li>
The reference value parameter for intSum() is now optional. 
As a consequence, if a variable name is used, it must not be a valid integer.
</li>


<li>
The supplied TCPClient implementation no longer treats tcp.eolByte=0 as special.
To skip EOL checking, set tcp.eolByte=1000 (or some other value which is not a valid byte)

</li>


<li>

Leading and trailing spaces are trimmed from variable names in function calls.
For example, ${__Random(1,63, LOTTERY )} will use the variable 'LOTTERY' rather than ' LOTTERY '.

</li>


<li>

Synchronization has been removed from the RunningSample class (it was not fully threadsafe anyway).
Developers of 3rd party add-ons that use the class may need to synchronize access.

</li>


</ul>
